Little black wire on carb

[By xti, Posted October 19, 2005]

Can someone please tell me what the black wire # 54 is that goes to the carb on the right side of carb to the left of the choke knob. This is on the Mikuni S version.

Just wondering what the purpose is?

Looks like throttle position sensor.

Thanks, Not sure how that works from looking at the drawing. Is it an electronic signal or vacuuum?

I also notice Suzuki makes a heater items 63 and 64. Anybody using it? Imagine it would help with cold starting issues.
